摘要
导电聚合物是超级电容器中一类常用的赝电容电极材料,具有较高的理论比电容;而石墨烯与导电聚合物复合,可以提高电极材料的电导率,改变电极材料的微观结构,进一步提高电极材料的性能。目前,导电聚合物/石墨烯复合电极材料存在如下问题:(1)倍率性能差,(2)循环稳定性低,(3)比电容有待提升。我们以聚苯胺为主要研究对象,设计了新的聚苯胺/石墨烯复合材料的复合方式及微观结构,并发展了新的制备方法,从而得到了高性能的聚苯胺复合电极材料。以此为基础,我们也对聚苯胺/石墨烯复合材料的结构与性能的关系做了系统的研究。
Conducting polymers are a widely-used type of electrode materials for supercapacitors,and they can provide large pseudocapacitance.The performance of conducting polymers can be further improved by incorporating graphene,which is able to increase the electric conductivity and change the microstructure of the composite.However,there are still several problems in the conducting polymer/graphene electrode materials,including low rate performance,low cycling stability,and unsatisfying specific capacitance.In this paper we focus on improving the performance of polyaniline/graphene composite.By carefully designing the structure of polyaniline/graphene composite materials,we successfully synthesize novel polyaniline/graphene composites with high specific capacitance,good rate performance and long cycling life.Besides,the relationship between the microstructure and capacitive performance of polyaniline/graphene composites is also investigated systematically.
